Question

What occurs in meiosis?

Answer 1

Mitosis and meiosis are the two kinds of cell division. When people say "cell division," they usually mean mitosis, the process of creating new body cells. Meiosis is the cell division process that results in the formation of egg and sperm cells. Meiosis is required for eukaryotic creatures to reproduce sexually, to enable genetic variety through recombination, and to correct genetic abnormalities.

Complete answer:
Meiosis is a type of cell division that produces four gamete cells by halving the number of chromosomes in the parent cell. For sexual reproduction, this procedure is essential to create egg and sperm cells. When sperm and egg combine to form a single cell during reproduction, the number of chromosomes in the offspring is restored.
Meiosis begins with a diploid parent cell, which has two copies of each chromosome. One round of DNA replication occurs in the parent cell, followed by two nuclear division cycles. The process produces four haploid daughter cells, each of which has half the number of chromosomes as the diploid parent cell.
Meiosis is comparable to, but distinct from, mitosis, a cell division process in which a parent cell divides into two identical daughter cells. Following one round of DNA replication in cells of the male or female sex organs, meiosis commences. Meiosis I and meiosis II are the two divisions of the process, and both contain several steps. Meiosis I is a type of cell division that occurs exclusively in germ cells, whereas meiosis II is identical to mitosis.
They are designated as prophase I, metaphase I, anaphase I, and telophase I in meiosis I, and prophase II, metaphase II, anaphase II, and telophase II in meiosis II. These phases result in a variety of products, despite the fact that the fundamental principles of each are the identical. In addition, in interphase, meiosis I is preceded by both G and S phases, but meiosis II is only preceded by S phase: chromosomal replication is no longer required.

Note:-
Mitosis is a necessary part of existence. A cell separates into two identical daughter cells during mitosis, which repeats all of its components, including its chromosomes. The steps of mitosis are tightly controlled by various genes because this process is so important. When mitosis is not properly regulated, health issues such as cancer might arise. Meiosis, the second type of cell division, ensures that each generation of people has the same number of chromosomes.
